Here's a look at the top offensive performers in each league for the week ending July 20:

International LeagueAndy Wilkins, Charlotte(.647/.647/1.588, 4 G, 11-for-17, 1 2B, 5 HR, 8 RBI, 0 BB, 2 K)
Wilkins' stock in the White Sox system has always been tied to his power, and that offensive tool was on full display last week. The left-handed slugger launched five blasts, including a pair on both Thursday and Sunday against Scranton/Wilkes-Bare, to give him 21 on the season, most in the IL and three more than second-place teammate Matt Davidson. Seven of those roundtrippers have come in July, his highest total in a month despit having played in just 15 games so far. He needs only two more homers to match his career-best total of 23 set back in 2011 with Class A Advanced Winston-Salem.Wilkins launches second homer

Pacific Coast LeagueShane Peterson, Sacramento
(.600/.625/1.400, 3 G, 9-for-15, 3 2B, 3 HR, 8 RBI, 1 BB, 2 K)
Even though he participated in Wednesday's Triple-A All-Star Game, Peterson returned from the break as refreshed as if he had taken it off. The left-handed outfielder had the first three-homer game of his career Thursday. Each of the three homers came in consecutive at-bats during the third, fifth and sixth innings and traveled the opposite way. "I felt like going into my [late] at-bats, I felt comfortable. Even though I didn't get a hit or anything, I felt good about those at-bats," he told MiLB.com. "To hit three home runs in a game, a lot of things have to go right, but I was doing a lot of things right in those last at-bats and just didn't get results. That's kind of how baseball is." Peterson finished off the week by going 6-for-10 with three doubles and four RBIs over the weekend. He owns a .320/.395/.468 slash line with eight homers and 65 RBIs in 97 games with the River Cats.Peterson hits third homer of the game

Eastern LeagueDevon Travis, Erie(.435/.480/.783, 6 G, 10-for-23, 2 2B, 2 HR, 5 RBI, 2 BB, 6 K, 1 SB)
After being drafted in the 13th round out of Florida State back in 2012, Travis became an intriguing prospect at the plate last year, when he put together a .351/.418/.518 slash line between Class A West Michigan and Class A Advanced Lakeland. An oblique strain kept him from jumping out of the gate quickly in Erie, but the right-handed second baseman is certainly making up for lost time now. Travis has hits in seven straight games and multiple hits in four of those games. His slash line in 19 July games stands at .347/.419/.453 and is .299/.351/.455 in 61 contests this season.Travis smashes home run

Southern LeagueAustin Barnes, Jacksonville(.421/.522/.895, 6 G, 8-for-19, 3 HR, 7 RBI, 4 R, 4 BB, 3 K, 1 SB)
Unlike Wilkins above, Barnes isn't exactly known for power. He hit only five homers last season and had only one in 2014 entering last week. In fact, the most interesting thing about the Marlins' No. 15 prospect has been his defensive mobility as he's played in a rotation among catcher, third base and second base since joining Double-A Jacksonville back in June. But then, he went deep three times between Saturday and Sunday at home against Pensacola to take his first career Player of the Week honor. Of his eight hits, three went over the fence. Still, even Barnes himself admitted it was nothing more than a hot week and not really indicative of a sustainable power surge. "I think baseball's just a funny game and I think it comes together sometimes," he told MiLB.com on Sunday. "I don't really hit for much power. I'm just trying to get good swings." Barnes is batting .302 with a .806 OPS, four homers, two triples, 21 doubles, 35 RBIs between the Suns and Class A Advanced Jupiter.Barnes belts second homer

Texas LeagueMax Muncy, Midland(.435/.606/.870, 7 G, 10-for-23, 1 2B, 3 HR, 16 RBI, 10 BB, 4 K)
The A's No. 13 prospect has always shown an ability to get on base -- no surprise given Oakland's organizational philosophy -- and he exhibited some nice pop with 25 homers (21 of which came at Class A Advanced Stockton) last season. The OBP remains high (.400, which would be a career-best if he can maintain that pace), but the power had been sapped for most of the first three-plus months of the season. It returned last week when Muncy's three blasts doubled his season total to six. He also drove in two or more runs, including five on Monday, in five games and ranks tied for second in the Texas League with 53 RBIs. Thanks to the high OBP, his .830 OPS also pits him third in that category for the Lone Star State's Double-A circuit.Muncy hits another grand slam

California LeagueJordy Lara, High Desert(.417/.483/.958, 6 G, 10-for-24, 1 2B, 4 HR, 11 RBI, 8 R, 4 BB, 3 K)
The Cal League, and High Desert in particular, can sometimes lead to some funky offensive numbers, but Lara is on one heck of a run even when compared to his peers. The right-handed first baseman/right fielder is on a 12-game hitting streak, during which he's batting .469 with a 1.296 OPS. The bulk of his power in those numbers came last week when he went deep four times. Lara leads active Cal Leaguers with a .345 average through 97 games and ranks third with a .978 OPS. For reference, those numbers stood at .260 and .757 in 98 games with Class A Clinton a season ago.

Carolina LeagueJustin Bloxom, Lynchburg(.429/.478/.905, 6 G, 9-for-21, 5 2B, 1 3B, 1 HR, 6 RBI, 3 R, 2 BB, 1 K)
Bloxom was released by the Nationals back in late June after he struggled some (.674 OPS) in his third straight trip to Double-A Harrisburg. It didn't take long for him to land on his feet though, as the Braves scooped him up soon after and sent him to Class A Advanced Lynchburg. The 26-year-old first baseman looks like he's found his bearings in his new organization. After entering the week with a .196 average through his first 13 games with the Hillcats, Bloxom went 9-for-21 (.429) in a week that saw him collect at least one hit in every game he played. His homer Sunday was his first with Lynchburg and second of the season through 54 games.

Florida State LeagueByron Buxton, Fort Myers(.500/.583/.900, 4 G, 10-for-20, 1 3B, 2 HR, 4 RBI, 6 R, 3 BB, 4 K, 2 CS)
It's only four games, but this is the type of exciting week Twins fans and prospect-philes all around were hoping to see much more of from baseball's top prospect this season. Of course, left wrist injuries got in the way in both Spring Training and in early May. Now back with Class A Advanced Fort Myers, the toolsy outfielder flashed all of his potential last week, collecting multiple hits in three straight games from Wednesday to Friday -- a stretch that also saw him homer in back-to-back games Thursday and Friday. The 2012 second overall pick washit in the same wrist by a pitch Friday and didn't play for the Miracle over the weekend.

Midwest LeagueTyler Marincov, Beloit(.400/.458/1.100, 6 G, 8-for-20, 3 2B, 1 3B, 3 HR, 8 RBI, 3 BB, 2 K, 1 SB)
Marincov needed a pick-me-up after batting just .157 with a .528 OPS in 22 games last month, and it looks like that has finally come for the 2013 eighth-rounder out of the University of North Florida. Not only did he have three multi-hit games last week -- more than in all of June -- but he also cranked three homers and added three doubles and a triple (compared to only one single). Though his slugging percentage stood at just .406 entering July, that stat is up to .449 following his stellar week for the Snappers.

South Atlantic LeagueRoss Wilson, Rome(.500/.542/1.000, 5 G, 10-for-20, 2 2B, 1 3B, 2 HR, 9 RBI, 7 R, 3 BB, 3 K)
Wilson has done his share of bopping around the Minors since the White Sox took him in the the 10th round back in 2010. He was released by Chicago in October 2012 but moved quickly to the Marlins system that same month. The Fish let the 25-year-old second baseman go on May 6 this season after stints at Class A Advanced Jupiter and Double-A Jacksonville, and he signed with the Braves 23 days later and was assigned to Class A Rome. The former Alabama infielder is starting to repay Atlanta for its faith in him. From Thursday to Sunday last week, he went 9-for-16 with two homers, a triple, two doubles and nine RBIs. His slash line is up to .258/.360/.396 with four homers and 23 RBIs in 43 games since joining Rome.

New York-Penn LeagueGrant Kay, Hudson Valley(.458/.519/.917, 6 G, 11-for-24, 3 2B, 1 3B, 2 HR, 4 RBI, 8 R, 3 BB, 5 K)
Kay had one of the most incredible debuts in recent memory, or perhaps even Minor League history, last Monday when he cycled in his professional debut with the Renegades. Drafted by the Rays in the 27th round back in June after his junior season at the University of Louisville, the 21-year-old infielder didn't decide whether to sign until earlier this month and was worried he wouldn't be able to make his pro debut until later in the week. Those fears were erased when he went 5-for-6 with three RBIs and five runs scored in the Renegades' 16-4 win over Batavia on Monday. He was solid the rest of the week, going 6-for-18 (.333) with another homer and two more doubles.

Northwest LeagueZach Cone, Spokane(.333/.387/.926, 7 G, 9-for-27, 4 2B, 4 HR, 10 RBI, 6 R, 2 BB, 4 K)
Cone was featured three weeks ago in the MiLB.com Northwest League notebook as he tries to rework his swing in his second go-round at Class A Short Season Spokane. That labor bore fruit last week, when he slugged four homers after entering the week with only three during his time with the Indians. He went deep once, doubled twice, drove in two and scored three times in Friday's 12-3 win over Everett. In 33 games with Spokane, the Rangers' 2011 first-rounder has a .224/.361/.500 line with seven homers (tied for most in the league) and 25 RBIs.

Appalachian LeagueWuilmer Becerra, Kingsport(.563/.563/1.250, 4 G, 9-for-16, 2 2B, 3 HR, 4 RBI, 4 R, 0 BB, 3 K)
Even though he hasn't played above Rookie level, Becerra's name should look familiar to Blue Jays and Mets fans alike. The Venezuelan outfielder was included with Travis d'Arnaud, Noah Syndergaard and Travis Buck in the deal that sent R.A. Dickey, Josh Thole and Mike Nickeas from the Mets to the Blue Jays back in December 2012. In his first season above the Gulf Coast League, the 19-year-old is handling the Appalachian League well, as he showed when he homered twice Monday and when he went 5-for-5 with two doubles and an RBI on Wednesday. Becerra owns a .307/.354/.520 line with four homers, four doubles and 10 RBIs in 22 games with Kingsport.

Pioneer LeagueZach Fisher, Great Falls(.640/.655/1.120, 6 G, 16-for-25, 4 2B, 1 3B, 2 HR, 14 RBI, 7 R, 3 BB, 1 K)
From a pure hitting standpoint, you couldn't ask for much of a better week than the one Fisher had. He has three or more hits in four of his last five games and finished off last week with perhaps the best performance of his career, going 4-for-5 with two doubles, six RBIs and a walk Sunday at Idaho Falls. In his second season with Idaho Falls, the 22-year-old catcher ranks third in the Pioneer League with a .376 average and sits fourth with a 1.025 OPS.
